This is when the magic begins! Maine Coon kittens grow rapidly as their eyes open and they start exploring their surroundings. You’ll notice their distinctive ear tufts beginning to form, and their playful personalities start emerging. This is also when their Maine Coon fluffy kittens characteristics become more apparent.
